IMPROVEMENT IN SPINNING-Mums.

Specication forming part of Letiers Patent No. 139,737, dated June 10, 1873; application filed February27, 1873. i

ToaZZ uhom it may concern:

Be it known that we, THOMAS HENRY RUSHTON, of the rm of Messieurs Dobson & Barlow, of Bolton in the county of Lancaster, in England, machine-maker, and ROB- ERT TOUGE, of the same place, foreman, have invented certain new and useful Improvements in Machinery for Spinning and Doubling; and we hereby declare the following to be a full, clear, and exact description thereof, reference being had to the annexed drawings forming part of this specification.

The 4object of the first part of our invention 1s to simplify the gearing of hand and selfacting mules for producing the after-stretch and for giving motion to the front roller during the twisting at the head; also, to render self-acting mules suitable for spinning fine numbers; secondly, in an improvcdarrangement of mechanism for locking the fallers and for unlatchin g the long lever,77 forming parts of a self-acting mule.

. Figure 1 represents the principal parts of a self-acting mule to which our improvements are applied. Fig. 2 is a plan, and Fig.3 an end view of the same. Fig. 4.- is a detached view of the mechanism forming the iirst part of our invention, and Fig. 5 a section of the same. Fig. 6 is a part of the said mechanism. Fig; 7 is a detached view of the mechanism forming the second part of our invention, and Fig. 8 a front view of the same.

ln Figs. 1, 2, and 3, a is the front roller coupling-shaft. b is the side shaft, and c is the shaft on which the scrolls for driving the care and f are the faller and counter-faller shafts; e', the sector and lever to which the backing-od" chain and faller-leg are suspended g, the long lever; and h, the latch by which it is held in position. Z is the backing-off scroll; j, the copping-rail which is acted upon by the Shaper-plates j', and k is the bowl running on the copping-rail. The parts above enumerated and the others required to complete the mule, and which are not shown or not described hereafter, are made in the usual manner. On the Jside shaft b is xed the mitcrwheel b1, shown best in Figs. 4 and 5, and this wheel gears into a similar wheel, a1, which is loose on the shaft ct. To the wheel al is cast part of a clutch-box, a,

which takes into the sliding clutch-box a3 which is cast or fixed to the spur-wheel (1,4: Within the wheel al is an internal sliding clutch-box, a5, which takes into the clutches a?. The spur-wheel a4 is loose on the boss of the sliding clutch-box ai To the shaft ais fixed the disk @$5,011 the circumference of which are four or other convenient number of snugs, and between any two of these snngs the pin projecting from the clutch-box a5 enters, as shown in Fig. 6. `To the miter-wheel b1 is cast or iixed the bevel-pinion b2, which gears into the wheel Z, mounted ou a stud 'fixed in a bracket bolted to the side of the head-stock. On the boss of the bevel-wheel Z is castor fixed a plate, Z1, having eight or other convenient number of slots containing the sliding catches Z2, which fall by their own gravity into gear with theinternal ratchet-wheel Z3 cast with thc carrier-wheel Z4. On the boss of the bevelwheel Z is mounted the gearing-lever m. The wheel a4 gears into the carrier-wheel Z4, which gears into the change-wheel m1 mounted yon a stud xed in a segmental slot in the gearing-lever, and the wheel m1 is fixed on the boss of the pinion m2, which gears into the Wheel c on the scroll-shaft c. The end of the gearing-lever m rests upon the short arm of the lever n, seen best in Fig. 3, and the longer arm of the same is acted upon by the stud at the end of the long lever g.

As long as the clutch-box a3 remains in gear with the clutches a2 on the miter-wheel al, the scroll-shaft c is driven and the carriage is taken out by the train of wheels a4, Z4, fm1, and

pinion m2, gearing into the wheel c; but` when the carriagehas arrived near the end of its stretch and the after-stretch is required, the clutch-box e3 is drawn out o f gear by the rollergear rod or otherwise, thereby liberating the spur-wheel a4, which then runs looseon the boss of the sliding clutch-box a5. The pinion b2 then becomes the driver, a-nd the catches Z2, taking into the,` ratchet-Wheel Z3, cause the wheel Z4 to rotate at the proper reduced speed for driving the scrollshaft during the after-stretch.

On referring to Fig. 6 it willbe seen that the pin projecting from the sliding clutchbox a5 is between the two snugs on the disk as that are nearest together, in order to start the rollers quickly; but in spinning iine numbers it is desirable to start the rollers slower, and for that purpose the pin must be changed into one of the larger spaces between the snugs. The greater the space between the snugs the slower the rollers will be started.

By making the spur-wheel a4 fast on the bossof the sliding clutch-box a5, by a setscrew or otherwise, a slow motion is imparted to the front roller during the after-stretch and while twisting at the head.

Our improved arrangement of mechanism for locking the fallcrs and for unlatching the long lever is shown in Figs. 1, 7, and 8.Y To the sector and lever c is suspended the fallerleg o, which is provided with a slot in which a pin, p1, projecting from the tumbler-lever p, slides. stud projecting from a bracket secured to the carriage. In the shorter arm of the tumblerlever p is4 a stud for the grooved pulley p2, around which the backing-oft` chain is taken. The faller-leg o has a projection, o', for catching on the bowl i" projecting from the usual slide-bar r. To the tumbler-lever p is fixed the adjustable fin ger p3, which acts, Vwhen the carriage is out, on the incline on the latch h. This latch holds down the outer end of the long lever g. When the carriage is going out the pinion m2 is in gear with the wheel c', and the long lever is held down by the usual catch, and when the carriage arrives out this catch is moved by a stud as usual. The stud at the other end of the long lever, then acting on the lever n, raises the end ofthe gearing-lever m and lifts the pinion m2 out of gear with the wheel c. The backing-oli' chain is then coiled This tumbler-lever is mounted on a.

on the scroll t' and pulls down the sector e thereby raising the faller-leg until the pro jection o comes over the bowl 1" in the slidebar 1", as shown in Fig. 7. The backing-olf chain then pulls the projection onto the said bowl, thus moving the tumbler-lever p, and this motion brings `the finger p3 against the incline on the horizontal arm ot' the latch h. The vertical arm of this latch then releases the end of the long lever g, which replaces the parts into the positions required for the running-in motion ofthe carriage.

What we claim herein as new, and desire to secure by Letters Patent ofthe United States, 1s

l. The combination of the bevel-gears b1 b2 al Zwith the spur-gears a4, l4,m1m2, the clutches a2 a3 a5, the ratchet l, and the plate l1 having the sliding catches l2, as and for the purpose described.

2. The combination of the roller-shafta with the disk a6, having snugs placed at unequal distances apart, and the sliding clutch a5 having a pin for engaging said snugs, as and for the purpose set forth. Y Y

3. The combination of the faller-leg o, having the shoulder o', with the tumbler-lever p and the adjustable linger p3, as and for the purpose specified.

In testimony whereof we have hereunto set our hands before two subscribing witnesses.
